My Tax Account is a separate system used for the purposes of Income, Sales and Excise Tax filing and payments. M-Form filers must be in the
Manufacturing Assessment System to view and access your accounts

Once you are in the Manufacturing Assessment System you can log into the Web Access Management System (WAMS) using your WAMS User ID and Password

"Authorized Accounts" page lists accounts you are authorized to access

If an account is already open by another authorized user, the State ID # is black and is not underlined. Hover over the ID number to see which other authorized user is in the account.

Can I download the pre-filled M-Form more than once?

Yes. Authorized users can download pre-filled M-Form.

A list of downloaded M-Forms is available on the "Account History" page until the form is filed

Only the M-Form that is
submitted first is accepted as a valid filing. After the first downloaded form is submitted, the other saved forms are deactivated and cannot be filed. This prevents multiple users from accidently overwriting each other's work.

I have a new location for my property. How do I report the new location?

Contact a Wisconsin Department of Revenue (DOR) appraiser at the
Manufacturing & Utility Bureau District Office in your area. After you explain the property location changes to the appraiser, he or she will inform you of your filing requirements.
